Cavity Wall Insulation

About 35% of all heat loss from UK homes is due to un-insulated external walls.

 

If your home was built after the 1930s, the chances are that its external walls are made of two ‘skins’ with a small gap between them. This means they are ‘cavity walls’ and the gap between them can be filled with insulating material to stop the warmth escaping to the outside.

A cavity wall can be filled with an insulating material by injecting beads into the wall. This restricts any warmth passing through the wall, reducing the money you spend on heating.

You can check your wall type by looking at your brick pattern.

 

If the bricks have an even pattern and are laid lengthways, then the wall is likely to have a cavity.

 

If some of the bricks are laid with the square end facing, the wall is likely to be solid. If the wall is stone, it is likely to be solid.

If your home was built within the last 25 years it is likely to been already insulated or possibly partially insulated. The surveyor can check this with a borescope inspection.

 

Bill savings and things to be aware of:

  • Can save between £145-£480 a year on your fuel bills depending on property size (Figures from the Energy Saving Trust and assume property is a gas heated home and sized between a flat to a detached home).

  • Walls are normally drilled and then filled from the outside, which minimises disruption and mess.

  • Can be completed in a few hours.

  • Grant funding is available that can cover the full cost of installation (qualifying criteria apply).
